Application filed May 11, 1909. Serial No. 495,352.

To all whom it concern:

Be it known that THOMAS PEAoooK, a subject of Great Britain, residing atJerome in the county of Yava ai and Territory 0 Arizona, have invent anew and useful Puzzle, of which the following is a specification. v

My invention relates to colored geometric puzzles, and the object is toprovide amuse ment or recreation inthe process of solving the puzzle.

The puzzle is constructed of a number of flat pieces of suitablematerial each havi its flat surfaces colored, and being forms intosquare, triangular -and other geometrical shapes, the whole, whenproperly joinedtogether forming a square in which, on' the face side, notwo pieces of the same color are adjacent at the sides thereof; or,similarly colored pieces may only touch at their respective corners. Allthe pieces, a

number singly, and the remainder by pairs,

' are reverslble -as regards size. and shape.

The difierent pieces are shaped as shown by the accompanying drawing,which is a view of the face sides of the various pieces when properlyjoined together, and'on which the various pieces are numbered.

There are three or morecolors used. The coloring of the upper or facesides of the pieces may be varied in any combination of three or morecolors, and the variations in the coloring of the separate pieces may beextended to a large number while only using the same number of colors.It is possible tomanufacture a very largenumber of puzzles in which notwo would be exactly similar in the coloring of the two flat surfaces ofeach separate piece while only using the same three colors. an example,in

one puzzle the face sides of the pieces num bered 1, 2, 3, 4, 8, 9, 14,and 15 may be of the first color, the coloring of the face sides of thepieces numbered 5, 7, 10, 11, 13, 17., and 19, may be of the secondcolor, and the coloring of the face sides of the pieces numbered 6, 12,16, 18, and 20 may be of the third color. The lower or reverse side ofeach piece is also colored in one ofthe same three or. more colorsusedon the face sides, but the coloring of the reverse sides ispromiscuous; thus for example, a piece havingthe first color on the faceside may be either of the first, second, or third color on thereversesiden The ob]ect of the pro miscuous coloring of the reversesides is intended to render the solution of the puzzle more difiicult.

. I claim:

A puzzle combination of twenty1 flat pieces of suitable material ofwhich t ree pieces are square, two are rhomboidal, fourteen aretriangular, and one is five sided, the sizes of each and all of thepiecesibein adjusted so that when all are joined togetier 1n the pro ermanner a square is f0rmed,-th e flat sur aces of the various piecesbeing colored on both sides in three different colors, the coloring ofthe separate pieces both on the face" and reverse sides thereof beingarranged so that a square may be formed in" which no two piecesadjacent, at the sides thereof are of the same color on the face side,as illustrated by the accompanying drawing.
